Even if "IPsec VPN connection using virtual appliance" and "ExpressRoute" coexist, does ExpressRoute have a higher priority from Azure to on-premise?

    @napblanket
    Yes, when VPN and Express route both co-exist, the ExpressRoute circuit is always the primary link from Azure to on-premise. Data flows through the Site-to-Site VPN path only if the ExpressRoute circuit fails. Please let us know if you have any more questions. Thank you!
